Supercrete Construction (R) Value Data Sheets

These data sheets have been produced in response to the publication of the BRANZ "House Insulation Guide" to give more accurate values for composite wall and floor systems taking into account the reduction in thermal resistance due to the timber or steel framing. The figures given do not take into account wall & door openings and the (R) Values for these can be calculated separately using the WINDOW or THERM software.

For ease of comparison the data sheets are in a similar form to those in the BRANZ publication "House Insulation Guide".

As for the BRANZ publication, the figures have been calculated using the methods in NZS4214:2006 Methods of Determining the Total Thermal Resistance of Parts of a Building.

NOTE: These sheets are to be read in conjunction with the Supercrete Soundfloor Joist Charts on this website. CRDS-3 through CRDS-10 are best used for comparing (R) Values with other floor systems and for determining which combinations of joist spacing & insulation type comply with the requirements of the New Zealand Building Code. CRDS-11 through CRDS-21 give exact figures for various joist spacings and insulation types.
